Hi @mastanggt,
We can not unblock your IP until you've upgraded to the 0.3.x release series. Otherwise you'll be missing the bug fixes that addressed the cause of the abusive traffic and will get blocked again.
When you upgrade make sure to go directly to v0.3.2. I believe 0.3.0 is missing support for the "ready" ACME order status and won't work.
When you've completed the upgrade to 0.3.2 let me know and I will begin processing the IP unblock.
Thanks!
